Q. What kind of transformation converts the graph of f(x)=−8(x+5)2−10 into the graph of g(x)=−8(x+4)2−10?Choices:(A) translation 1 unit up(B) translation 1 unit left(C) translation 1 unit right(D) translation 1 unit down
Identify Vertex: Identify the vertex of the function f(x). The function f(x)=−8(x+5)2−10 is in vertex form, where the vertex is at the point (−5,−10).
Compare Vertices: Identify the vertex of the function g(x). The function g(x)=−8(x+4)2−10 is also in vertex form, where the vertex is at the point (−4,−10).
Determine Shift Direction: Compare the vertices of f(x) and g(x) to determine the type of transformation.The vertex of f(x) is (−5,−10) and the vertex of g(x) is (−4,−10). The y-coordinates are the same, so there is no vertical shift. The x-coordinate of g(x) is 1 unit greater than the x-coordinate of f(x), indicating a horizontal shift.
Match Transformation: Determine the direction of the horizontal shift. Since the x-coordinate of the vertex of g(x) is 1 unit greater than the x-coordinate of the vertex of f(x), the graph has shifted 1 unit to the right.
Match Transformation: Determine the direction of the horizontal shift. Since the x-coordinate of the vertex of g(x) is 1 unit greater than the x-coordinate of the vertex of f(x), the graph has shifted 1 unit to the right.Match the transformation to the given choices. The graph of f(x) has been shifted 1 unit to the right to obtain the graph of g(x). This corresponds to choice (C) translation 1 unit right.
